Outcomes

Primary Outcome Measures

Evaluate hemagglutination inhibition (HI) immune responses
Evaluate hemagglutination inhibition (HI) immune responses to two doses of 15μg A/H5N1 achieved in the antigen plus VEP group versus the antigen alone group (Group 3 vs. Group 2) at Day 42 using standard serological parameters (Geometric Mean Titer [GMT], Geometric Mean Fold Ratio [GMFR], seroconversion and seroprotection).

Secondary Outcome Measures

Safety of 15µg and 30µg IM A/H5N1 antigen administered with the 50µg VEP
Comprehensive assessment of solicited and non-solicited local (vaccination site) and systemic adverse events (AEs) Safety follow-up through six months after last vaccination
Characterize HI immune responses
Characterize HI immune responses in the 15µg A/H5N1 antigen alone group (Group 2) and the 15µg A/H5N1 antigen plus VEP group (Group 3) to determine if levels meet or exceed EMA CPMP/BWP/214/96 criteria for immunogenicity: The percent of subjects achieving seroconversion for HI antibody titer should meet or exceed 40% The percent of subjects achieving an HI antibody titer ≥ 1:40 should meet or exceed 70% GMT increase > 2.5

5. Study Description

Brief Summary
Groups 1 to 3 will receive two vaccinations on Day 0 and Day 21. Group 1 will receive 3.8µg A/H5N1 antigen formulated with AS03 adjuvant, administered by IM injection. Group 2 will receive 15µg A/H5N1 by IM alone. Group 3 will also receive 15µg A/H5N1 antigen administered IM but followed by the topical application of a VEP at the vaccination site. Group 4 will receive a single vaccination on Day 0 of 30µg A/H5N1antigen by IM, followed by application of a VEP at the vaccination site. The VEP (Vaccine Enhancement Patch) contains 50 mcg LT (heat-labile enterotoxin of E. coli)
